ORE-PULVERIZER.

SPECIFICATION forming part of Letters Patent No. 424,515, dated April 1, 1890.

Application filed November 2'7, 1889- Serial No. 331,828- (No model.)

To all whom it may concern.-

Be it known that I, THOMAS HENRY TRE- GONING, a subject of the Queen of Great Britain, residing at Cambrone, county of Cornwall, England, have invented a new and useful Ore-Pulverizcr, of which the following is a specification.

It is well known that in the reduction of the various ores it is necessary to first grind To the ore fine. This is done more easily by flushing the ores with water during the grinding process.

The object of my invention is to provide a machine that will pnlverize the ore rapidly i5 and finely, and in which the ore can be eas ily flushed. I attain this result by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the entire device; Fig. 2, a plan or top view of the bedplate and disks with the upper part of the machine removed, and Fig. a part section on the line X.

Similar letters refer to similar parts through- 2 5 out the several views.

In the accompanying drawings, A is the frame of the machine, and should be made sufficiently heavyto stand the strain to which it is subjected. It is made round, as shown,

0 to contain the ore and gears, and is provided on one side with. a spout or opening 13, through which the ore and water are drawn after the ore is pulverized, The mouth of the spout B is provided with two slides O,

5 which can be adjusted at a suitable height to allow the overflow of water and refuse to pass out over the top, It will be seen that as the ores are ground the valuable parts, being ground fine and flattened, will pass out with the water over the top of the slides, while the worthless parts will settle.

Inside the frame A and upon the bottom of the round basin-like portion of the frame is a bed-plate D. This plate is provided with 5 numerous grooves E, something similar to those of a millstone. The bed-plate is also provided near its outer edge with a set of upright teeth T, the object of which will be shown hereinafter.

Arranged within the frame A and upon the bed-plate D is a series of gears or disks F. These gears are made with the inside or core square, although I do not confine myself to this shape, so that the particles of ore will be caught between the bottom of the gears F and the bed'plate D and ground to powder. The central gear is fastened upon and turned by the vertical shaft H. The other gears or disks F mesh with the central gear, so that when this is turned in one direction the other gears will turn in the opposite direction, as indicated by the arrows in Fig. 2. The gears or disks are kept in proper alignment by the upright teeth T. These teeth are arranged around the edge of the bed-plate D, so as to o mesh with the gears F. The gears are thus prevented from being crowded out, and when the machine is in operation they will revolve upon their own axes and also around the central gear. The partially-crushed ore and water are introduced through the hopper I and spout J into a second hopper K. This hopper is placed around the shaft H and directly above the center gear, so that the ore will pass down through the center gear and be ground between the several gears and the bedplate D.

To clean out the machine, the loose gears are removed, the slides C raised, and the powdered ore scraped out through the spout B. I have shown five gears in the drawings, and I find that a convenient number; but I do not confine myself to that number, as any number from two up may be used.

The bed-plate D is centered by the wedges L, arranged on three sides of it and between it and the frame A.

Having fully described my invention, what I claim as n ew, and desire to secure by Letters Patent, is

1. An orepulverizing machine consisting, essentially, of a frame provided with a grooved bed-plate, a central gear-wheel fixed to a vertical shaft so as to turn fiatwise upon said bed-plate, two or more gears or disks adapted to turn flatwise upon said bed-plate and to mesh with and revolve around said central gear, and a series of vertical studs or teeth afranged around the edge of the bed-plate to the revolving gee rs or disks F, substantially hold the gears in position thereon, substanas set forth. tially as described.

2. An ore-pulverizing machine having the THOMAS HENRY TREGONING' 5 basin-like frame A, said frame containing the \Vitnesses:

bed-plate D, grooved as shown, and provided RICHD. ROWE,

with the "ertical teeth T, in combination with JAMES J. TREGONING.
